MANIFOLDING MACHINE.

.Application led September 19, 1927. Serial No. 220,359.

My invention relates to paper guiding and tensioning racks vfor use withcertain types ofI manifolding machines in which the paper webs are drawnalong by hand over the platen of the machine and then dropped over studsor pins at the end of the platen, said studs engaging in holes formed inthe paper webs. In such machines the paper is usually printed into formswhich are alike for any given operation, and the primary requisite ofsuch machines is that the various blanks in the forms should be broughtinto correct alignment with each other where the paper is to be writtenupon. The paper is brought from a point of storage up and across thewriting machine platen, or autographie writing support, as the case maybe,

and carbon paper or other means is interleaved with the and transversethe said webs.

- The feature which is provided for `by my present mechanism results inbringing the paper webs to true alignment over the studs or pins whichare hooked into the several forms on the platen by pulling back on thewebs after they are hooked over the pins. Such a device is known as atensioning`de vice, and there are several types on the market.

In illustrating my invention I have shown it as applied to a flat bedmanifolding typewriter machine which I have selected as typical of thetypewriting manifolders, but it will be just as applicable to any kindof a mechanism where there are pins located at the endof the platen, anda tensioning device is required to pull the Webs of paper transferringseveral webs back toward the storage, after they havebeen dropped overthe pins.

I accomplish my objects by that certain construction and arrangement ofparts of which I show and describe two forms typical of others which arepossible, and the novelty of which will be set forth in the appendedclaims.

In the drawings Figure 1 is a side elevation of a manifolding typewritermachine.

Figure 2 is a perspective detail showing the mounting of theslat frameand the roller frame with relation to each other, in my first form ofstructure.

Figure 3 is a perspective view of the roller frame and roller assembly.

'Figure 4 is a perspective of the slat frame and slat assembly.

Figure 5 is a detail plan view partly in section showing the mounting ofthe slat frame on the roller frame.

Figure G is a detail side elevation showing the slat frame androllerpfrai'iie of my second form in displaced relation.

Figure 7 is a like View showing said parts in working relation.

Figure 8 is a perspective of the slat frame of my second form ofstructure.

Figure 9 is a perspective of the roller frame of my second type ofstructure.

I have illustrated a frame 1 on which is mounted a typewriting machine 2which moves to and fro laterally and also forward and back on the frame.The platen of the machine is located beneath the path of movement of thetypewriting machine, and the studs or pins (not shown) are at the end ofthe machine away from the'paper storage. The paper la is shown as beingstored in a large Vcompound roll E22L which contains a series of websdifferentially wound so as to feed oft' in such a Way as to bring theprinted forms thereon into alignment over the platen, and maintainsufiicient paper between the roll and the aligning pins to permit ofpreservation of the alignment.

The flat bed manifolding typewriter machine is provided withside bars towhich one or the other of the frames forming part ofmy invention areattached. These bars are illustrated at 3 in Figure l, and the rack uponwhich the line spacing mechanism of the typewriter operates is securedto these side bars. y Referring to the rst of the two forms of deviceillustrated, I have shown a frame 4, which may be rectangular in shape,in which are rigidly mounted a series of bars 5. There will be one barfor each web of paper that is to be employed. The bars have fastthereon, or slidable thereon the slotted plates 6. These plates havetheir slots depending at a slant, and rollers 7, which act by gravity inthe slots, are provlded with spindles 7 which lie within the slots.

The slat framefS is also rectangular to fit the roller frame, and isprovided with a series of slanting slats 9 extending across them soarranged that thegravity rollers will rest on and roll up and down onthe slats.

When the two frames are mounted together, aswill be described, the paperwebs are brought up, one over each Slat, then down over the slat andback up over the roller which lies on the slat from whence it is fedacross the platen of the machine.

When a section of all webs is pulled forward and set over the aligningpins, the gravity rollers will ride up during the advance, and as soonas the paper is released, Will ride down along the slats, thus pullingback on the paper slightly, and aligning it by means of the aligning pinengagement.

`My invention becomes of importance when it comes to the insertion `ot anew set of forms in the machine, in which case I rovide for some kind ofa separation of the slat frame and the roller frame, which leaves thespace clear for the operator to work, and still retains the'two framesso that when they are set back into operating. position, the paper willbelcorrectly engaged.

Referring again to the first form of the device, I have provided aseries of studs 10 in the roller frame, which are placed in bayonetslots l1 in the slat frame. The slat frame will b e just enough smallerthan the roller frame that it will slide up into the roller frame frombeneath, and the bayonet slots are such that when the studs 10 lie inthe tops of the slots, the slat frame will have moved down Asuiicientlyto clear the rollers in their lowermost position and permit easythreading through of paper webs. `When the slat frame is raised, and thestuds are set in the notch in the lower endof the bayonet slots, thenthe slats are brought up into position of contact with the rollers.

It `would be practical to hinge the frames at one end, or latchk them insome kind of a way into two positions, all of which would to an extentaccomplish my object.

In my second form, however, I have shown another arrangement in whichthe slat frame and the roller frame are spaced from each other inparallelism.

Thus I have shown in Figure 8 a slat frame 20 having slats 21, said slatframe being mounted fast in the side bars of the machine. The rollerframe 22 is just alittle smaller than the slat frame, and is intended tobe seated therein.

In the roller frame there are the fixed cross bars 23 on which aremounted the spaced slotted pieces 24, which in this case extend upwardlyat a slant. The roller 25 rides in the slo The lower edge of the sideframe pieces of the roller frame are provided with notches to engageover the slats in the slat frame, thus positioning the roller frame incorrect relation to the slats. Thus I have shown the notches 26 alongeach side of the frame, said notches having the intermediate notchtongues 27.

When in operating relation the roller frame .is set into the slat frameso that the slats 11e in the upper ends of the notches.

lVhen it is desiredv to charge a new set of forms the roller frame islifted, which can be done by sliding it forwardly of the machine, sothat it rides up along` the notch walls. lVhcn the frame has passed to aposition where the tongues 2T will engage over the tops of the slats theroller frame will rest in this position. The rollers will be thus alllifted away from the slats. and the operator will have space to chargein the new set of forms, whereupon the roller frame is lifted slightlyand slid back into place for regular operation.

It will be understood that by referring to slats and a slatframe, that Iintend to include any type of cross member such as bars,- large rolls,curved strips or the like. The term Slat is used for convenience asreferring to a cross member in a structure of the type noted.

Having thus described typical structures embodying my invention, what Iclaim as new and desire to secure by Letters Patent, 1s:-
